1. Calcarea carbonica: This remedy is often prescribed for individuals who have weak or brittle bones, slow development, and difficulty in calcium absorption. It may also be considered for those with calcium deficiency symptoms, such as muscle weakness, fatigue, and general sluggishness.
2. Calcarea phosphorica: This remedy is sometimes used for conditions where there is a deficiency of both calcium and phosphorus. It is often recommended for growing children, pregnant or lactating women, and individuals with weakened bones or slow healing fractures.
3. Silicea: This remedy is used for conditions where there is a lack of calcium absorption due to weak digestion or poor assimilation. It may be considered when there are symptoms such as brittle nails, weak teeth, and a tendency to perspire excessively.
4. Symphytum: This remedy is often recommended for promoting healing of bone fractures and injuries. It is primarily used as a supportive remedy to aid in the healing process rather than directly addressing calcium absorption.
